SANDING DEVICE FOR AUTOMOBILES.

Specification of Letters Patent.

Patented Apr. 25, 1916.

To all whom it may concern Be it known that 1, CHARLES L. LINCOLN, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Sanding Device for Automobiles, of which the following is a full, clear, and exact description.

The invention relates to sanding devices for automobiles, such as shown and describe in the Letters Patent of the United States, No. 1,112,301, granted to me on September 29, 191%.

The object of the present invention is to provide a new and improved sanding device for automobiles and similar vehicles and which is very simple and durable in con struction and arranged to permit the driver of the automobile to control the discharge of the same or other dry, non-packing material, either in a large quantity at the peripheral face of the drive wheel and the roadway, or in gradually lesser quantities on the roadway in front of the drive wheel.

In order to accomplish the desired result, use is made of a nozzle connected with a suitable supply of sand or other dry, nonpacking material, the nozzle being mounted to swing toward and from the drive wheel of the automobile, and a closure for said nozzle controlled by manual means to normally hold the closure in closed position and to gradually open the nozzle on swinging the latter rearward.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the sanding device as applied to an automobile, parts being shown broken out; Fig. 2 is an in verted plan. view of the sanding device; and Fig. 3 same.

A transverse shaft 10 is'journaled in suitable bearings 11 attached to the under side of the running boards 12 of an automobile or similar vehicle 13 and on one end of the said shaft 10 is secured a crank arm 1 1 connected by a link 15 with a hand lever 16 extending within the reach of the driver of the vehicle to enable the driver to impart a swinging motion to the lever 16 is a sectional side elevation of the with a view to rock the shaft 10 for the purpose hereinafter more fully described. On the shaftlO are secured tubes 17 arranged 1n ahnement with the rear or drive wheels of the vehicle 13 and the said tubes 17 are connected by hose or other flexible tubes 18 with pipes 19 leading from the hoppershaped bottom of a container 20 mounted on the vehicle 13 at any convenient place, preferably under the rear seat. The container 20 is adapted to contain fine gravel or dry, coarse sand or similar dry, nonpacking material adapted to flow through the pipes 19 and tubes 18 to the tubes 17 to normally fill the latter.

The free end of each tube 17 is provided with a nozzle 21 normally closed by a cover or similar closure 22 pivoted on the nozzle and provided with an arm 23 connected by a link 24 with a bracket 25 attached to the under side of the corresponding running board 12. The closure 22 is provided with a facing 26 of rubber or other suitable co1npressible material to tightly close the mouth of the closure 21 while the latter is in f0rward position, as shown in the drawings.

When the parts are in the position illustrated in the drawings, and it is desired to sand the roadway in front of the rear or drive wheels then the driver imparts a swinging motion to the lever 16 in a forward direction so that the shaft 10 is rocked and the tubes 17 swing downward and rearward, and during this downward and rearward movement of each tube 17 the closure 22 remains closed until the link 2 1 has passed the vertical position, and then on a further rearward swinging movement of each tube 17 the closure 22 is gradually opened to allow the dry, non-packing material contained in the tube 17 and the nozzle 21 to flow down onto the roadway.

13y reference to the drawings it will be noticedthat the fulcrum of the link 24 on the bracket 25 is a distance forward of the fulcrum of the tube 17 and hence when the link has passed a vertical position during the downward and rearward swinging movement of the tube 17 the closure 22 thereof is gradually swung open. Thus if the driver desires to sand the roadway but slightly the lever 16 is swung correspondingly forward, that is to say, the nozzle 22 swings into a slightly open position and after the sanding has been completed the lever 16 is returned to rearmost position to cause the tubes 17 to return to forward upward closed position. to discharge a large quantity of sand onto the roadway and onto the peripheral face of the rear or drive wheel then the driver swings the lever 16 forward to the full extent, as indicated in dotted lines in Fig. 1,

so that the tubes 17 swing rearwardly a sufiicient distance to locate the nozzle 21 immediately in the front of the rear or drive wheels with the closures completely open to allow the dry, non-packing material to flow out of the nozzle in a. rearward and downward direction onto the peripheral face of the drive wheel and the roadway immediately in front of the drive wheel. After the sanding has-been accomplished, the lever 16 is returned to normal position whereby the tubes 17 are swung forward and upward to normal position of rest, and during this movement the closure 22 is swung into closed position by the action of the link 24 on the arm 23. It is understood that the elastic packing 26 yields sufliclently during the final closing movement of the closure to insure a firm closing of the nozzle 21 at the time the parts reach normal inactive position, as shown in the drawings.

From the foregoing it will be seen that by the arrangement described, the driver of the automobile controls the discharge of the sand in small or large quantities, as desired and either at or a distance in front of the rear or drive wheel. It is understood that on the rearward swinging motion of the tube 17 the non-packing material is forcibly ejected and by making the nozzle sufiiciently wide the non-packing material is scattered a sufficient width beyond both sides of the wheels atthe contact point of the wheels with the ground to prevent slipping o-r skidding.

The sanding device shown and described is very simple and composed of comparatively few parts not liable easily to get out of order. It will also be noticed that the sanding device can be readily applied to automobiles and other vehicles as now generally constructed.

Having thus described my invention, I

When it is desired claim as new ters Patent:

1. A sanding device for automobiles and similar vehicles, comprising a container adapted to contain a dry non-packing material, a nozzle connected with the said container and normally extending forwardly in an approximately horizontal position, the said nozzle being mounted to swing downward and rearward beyond a vertical position and back to normal forward position, a closure normally closing the said nozzle, and means connected with the said closure to begin opening the latter on the nozzle reaching an approximately vertical position and to gradually continue the said opening movement as the nozzle continues its swing backward to its rearward limit.

2. A sanding device for automobiles and similar vehicles, comprising a container adapted to contain a dry non-packing material, a tube connected with the said container and mounted to swing forward and backward in front of a rear or drive wheel of the automobile, a nozzle on the free end of the said tube, a closure pivoted on the said nozzle and normally closing the same, a link pivoted at one end on a fixed part and pivotally connected at its other end with the said closure, and manually controlled means connected with the said tube to swing thelatter rearwardly from normal forward closed position into rearward distributing position.

3. A sanding device for automobiles and similar vehicles, comprising a container adapted to contain a dry non-packing ma terial, a rock shaft, a lever under the control of the driver and connected with the said rock shaft, a tube attached to the said shaft and connected with the said container, a nozzle on the end of the said tube, a cover pivoted on the nozzle for normally closing the same, and a link pivoted at one end on a fixed part and pivotally connected at its other end with the said cover.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
